从XML获取元素

Question

I want to get the elements from a XML that can be fetched from a URL.

I have written the following code

import xml.etree.ElementTree as ET
url = 'https://www.sec.gov/Archives/edgar/data/1568219/000156821918000001/primary_doc.xml'
    req = ulib.Request(url)
    primaryXML = ulib.urlopen(req)
    xmlData = primaryXML.read()
    content = ET.fromstring(xmlData)

The XML that is available is

<edgarSubmission xmlns="http://www.sec.gov/edgar/thirteenffiler" xmlns:com="http://www.sec.gov/edgar/common">
<headerData>
<submissionType>13F-HR</submissionType>
<filerInfo>
<liveTestFlag>LIVE</liveTestFlag>
<flags>
<confirmingCopyFlag>false</confirmingCopyFlag>

</formData>
</edgarSubmission>

I want to get the value of submissionType

When I try

content.find("edgarSubmission/headerData/submissionType")

I dont get any result. I want to get 13F-HR

Can someone please explain what I am doing wrong ?

Answer 1

Try this. If 13F-HR is your only requirement to fetch, the script should do that.

import requests
from lxml.html import fromstring

res = requests.get("https://www.sec.gov/Archives/edgar/data/1568219/000156821918000001/primary_doc.xml")
tree = fromstring(res.content)
item = tree.cssselect("submissionType")[0].text
print(item)

OR

from urllib.request import urlopen
from lxml.html import fromstring

res = urlopen("https://www.sec.gov/Archives/edgar/data/1568219/000156821918000001/primary_doc.xml")
tree = fromstring(res.read())
item = tree.cssselect("submissionType")[0].text
print(item)

Output:

13F-HR
